Abstract

We propose a neutrino mass matrix model in which five neutrino species remain light through the seesaw mechanism within a supersymmetric 3νL+3νR3\nu_L+3\nu_R framework. We construct such a model based on the nonrenormalizable terms in the superpotential constrained by the discrete symmetry which may be expected in the models at the high energy scale such as superstring. We study the possible oscillation phenomena by fixing mass parameters so as to explain the solar and atmospheric neutrino deficits and also include a candidate of the suitable dark matter. We also discuss the charged lepton mass matrix based on this neutrino model. LSND results may be consistently explained within this model.
